Sandreck - Leading China Spiral Classifier Manufacturer
Sandreck, a China-based professional spiral classifier manufacturer with global operations, is a major supplier specializing in mineral processing equipment.
Our spiral classifiers are used in mineral processing to separate slurries by particle size. They are widely used for classifying metals (iron ore, tungsten ore) and non-metallic minerals, removing coarse sand, and classifying slurries by size. They also excel in controlling particle size in ore settling and in seed recovery.
We customize spiral classifiers to your specific needs. Whether you are beneficiating metal ores (iron, copper, lithium), grading construction aggregates, or treating environmentally friendly tailings, we have the right model for you.
Sandreck offers single- and double-spiral designs, high-weir classifiers for coarse-particle classification, and decanter-centrifuge classifiers for fine-particle classification. All of which help you achieve precise particle separation.
Product By Features
It has a small structure and low cost, and it can be used in small-sized and medium-sized mineral processing mines.
With its strong, durable construction, setup is simple, and it can be easily constructed and even operated by a single person with little effort.
With a higher settling pool and higher settling depth. It is good for classifying the fine material (-100 to -200 mesh).
It is employed in the classification and desliming of large quantities of fine iron ore (-20 to +100 mesh).
Spiral Classifier Advantages
Based on the spiral rotating chute, the synergistic effect of gravity and water on the separation efficiency of the spiral classifier is maximized.
Wear on the spiral blades, shell, and trough body is greatly reduced, and the spiral blades are lined with high-manganese steel and wear-resistant plates.
The Sandreck spiral classifier has a slotted design, making it easy to discharge equipment parts, maintain them, and reduce downtime.
The lifting mechanism can adjust the spiral height and flexibly adapt to slurries with different concentrations and particle sizes.
The low-speed, high-torque transmission system runs smoothly, and its power consumption is 60%-70% of that of similar equipment.
As a large-scale equipment manufacturer, we sell our spiral classifiers to customers at a standard price.
Modular Design
Sandreck employs a modular design, precision-engineering the spiral classifier body into independent modules, such as the tank and spiral assembly.
This not only standardizes production but also enables you to perform maintenance and part replacements as easily as working with building blocks. The result is significantly reduced downtime and guaranteed continuous operation for your plant.
Intelligent Anti-Clogging Lifting System
We understand the startup challenges caused by settled sands. Sandreck’s spiral classifier features an intelligent lifting system. With a simple one-button operation during shutdown, the spiral is effortlessly raised, fundamentally eliminating the risk of “machine burying” and protecting your motor and drive system from damage.
Wear-resistant Core Components
When it comes to wear resistance, Sandreck’s spiral classifier doesn’t cut corners. We apply specialized wear-resistant composite materials to key areas, including the spiral blades, main shaft, and tank liner.
This directly reduces wear for you, extends service life, and lowers your total cost of ownership.
How does a Spiral Classifier Work?
A spiral classifier is like a “smart sieve” for ore slurry. Its ingenious mechanical structure automatically separates the ground slurry into two parts.
Coarse particles sink to the bottom (return sand), and fine particles overflow (overflow).
This not only prepares the slurry for the next separation step but also returns unqualified coarse sand to the mill for further grinding, making it an indispensable aid in the grinding circuit.
Why Choose A Sandreck Spiral Classifier?
With so many options on the market, why trust Sandreck?
The Sandreck spiral classifier utilizes a modular manufacturing process, breaking the main unit down into modules such as the tank body, spiral assembly, and control system. These modules are manufactured separately and then precision-assembled. This approach not only minimizes manufacturing errors but also reduces installation time (installation can be completed within three days).
Our spiral classifiers offer an optional intelligent lifting system that allows the spiral to be raised with a single click during downtime, preventing sand from burying the classifier and preventing it from starting. This protects the equipment and saves time and effort.
Sandreck understands that every mine’s ore is unique. We offer professional selection services and can customize our spiral classifier to your specific needs, ensuring it perfectly matches your production line.
